Hi @acidyo ! I have the yo-yo weight problem myself. If I am active and I eat a mostly keto diet with no sugar, it seems to help a lot. I replaced sugar with honey for my coffee. It was an adjustment, but, now I can't tell the difference. Honey is still sugar, but, it is more natural. I don't starve because you have to eat a lot of meat for keto. I lost 25 kilos (see Americans can use the metric system) in about three months.
Good luck with your weight loss. I know you can do it!
